mysql_secure_installation

SYNOPSIS
mysql_secure_installation
DESCRIPTION
This program enables you to improve the security of your MySQL
installation in the following ways:
o You can set a password for root accounts.
o You can remove root accounts that are accessible from outside the
local host.
o You can remove anonymous-user accounts.
o You can remove the test database (which by default can be accessed
by all users, even anonymous users), and privileges that permit
anyone to access databases with names that start with test_.
mysql_secure_installation helps you implement security recommendations
similar to those described at Section 2.10.4, "Securing the Initial
MySQL Accounts".
Invoke mysql_secure_installation without arguments:
shell> mysql_secure_installation
When executed, the script prompts you to determine which actions to
perform.
